Project #405 - Anthropogenic Impact on Weathering Processes

Project Leaders: P. Sulovsky and J. Zeman

Czech Representatives: P. Sulovsky (email: sulovsky@muni.sci.cz) and J. Zeman

This project was on extended term status in 2001 and major focus was put on the preparation of the final book. Czech WG organized an Intensive Course of IGCP #405 Project on "Environmental Aspects of Weathering Processes" (September 9 - September 25 5, 2001).

The case localities showing impact of anthropogenically induced or influenced weathering on the environment, were located across the whole Czech Republic:

* forest decay due to enhanced weathering of base-cation poor bedrock (Erzgebirge and Jizera Mts, NW and N Bohemia)

* weathering of massive burning coal heap in (Radvanice, NE Bohemia) and associated release of heavy metals and radionuclides

* acid in situ uranium leaching (Straz p.R., N. Bohemia)

* acid mine drainage site in Chvaletice, weathering of industrial waste - fly ash (central Bohemia)

* impact of conventional uranium mine flooding (Rozinka, S Moravia)

* weathering of building and decorative rock materials (sandstone structure of the Charles Bridge and other historical buildings in Prague)

* weathering of U- and Th-rich igneous rocks and environmental problems associated with this process (Trebic Massif, W Moravia)

The course was organised and led by the IGCP 405 project leaders (P. Sulovsky, J. Zeman) and Dr. Vala Ragnarsdottir from Bristol University and Jorg Matschullat of the Technical University of Freiberg. The course materials prepared by Petr Sulovsky (textbook on CD-ROM and on a Web) were distributed among the course attendants and are presented on the Internet, together with photographs and video sequences taken during the trip.

 

Project #428 - Climate and Boreholes

Project Leaders: V. Cermak, H.N. Pollack and C. Clauser

Czech Representatives: V. Cermak (email: cermak@ig.cas.cz) and J. Safanda

2001 was the fourth year of the Project, where the Czech WG has significantly participate in the organizing and processing of the data from boreholes. When the first attempts to decipher information on the past climate from the underground temperature field have dated back to the early seventies and the corresponding studies become in principle known ten to fifteen years ago, it is basically due to this project that the "geothermal method" to reconstruct the past climate changes by the inversion of the borehole temperatures has been fully recognised as a tantamount tool of the palaeoclimate studies.

Achievement of the project in 2001 (Czech contribution): Fifth International Conference "Terrestrial Heat Flow and the Lithosphere Structure" was organized in Kostelec, Czech Republic, June 6-10, 2001 with a full week programme with two days reserved especially for the IGCP428 project. The scope of the meeting and its basic organization followed the successful tradition of four previous meetings held in the Czech Republic in 1982, 1987, 1991 and 1996. The scientific programme in addition to selected invited lectures completed with shorter contributing papers was based on an ample discussion and on an exchange of ideas together with an extensive poster session. Total of 65 attendees from 20 countries representing a sizeable part of the present heat flow community, presented 26 contributions within the session on "climate and boreholes". The selected contributions presented during this session will be published as a special issue of Global and Planetary Change journal together with several national reports. This special issue should also serve as a final volume reporting the results of the whole project, which will terminate in 2002. The scope of the session addressed the general climate and boreholes investigations, inversion of temperature data for the ground surface temperature history-reconstruction, long-term temperature monitoring in boreholes, scale climate studies on various time scale from recent to Pleistocene, climate change and recent warming, geothermal/meteorological data, air/soil temperature coupling and permafrost studies. As an additional meeting of the project 428 a special symposium "Temperatures within the Earth" was organised as a part of the Joint IASPEI - IAGA Assembly at Hanoi, August 25, 2001, convened by Ilmo Kukkonen (Finland) and Vladimir Cermak (Czech rep.). 25 attendees from 10 countries presented 17 papers (oral and poster).

Project #429 - Organics in Major Environmental Issues

Project Leaders: J. Pasava and J. Jenik

Czech Representative: B. Kribek (email: kribek@cgu.cz)

2001 was also the fourth year of this Project. The activity of the IGCP 429 WG was concentrated on the following topics:

Further for society very useful applied scientific results have been reached by Czech scientists on the weathering of fossil organic matter in waste dumps of coal mines of various age from the Sokolov Basin (Tertiary), Pilsen Basin (Carboniferous) and Barrandian Basin (Devonian). Oxidation of fossil organic matter in relation of coalification degree was studied experimentally. The result of the study showed that the rate of weathering of fossil organic matter depends on the organic matter type and degree of coalification. In the low degree of coalification, weathering of organic matter yields a great amount of humic substances. No humic substances are produced during weathering of black coals. The formation of humic substances increases adsorption capacity of anthropogenic soils. In contrast to soil humic acids, humic acids formed in a course of weathering are low of nitrogen. The gradual increase in their nitrogen contents during weathering is probably due to the interaction of weathering products of fossil organic matter with nitrogen-rich products of microbial activity. A part of weathered fossil algal-type organic matter in a low maturation degree may be directly metabolized by soil biota. These results can be very important for remediation strategy of dumpsite after coal mining worldwide.

The study of behavior of selected trace elements in liassic black shales, associated soils and vegetation in the abandoned mining district in the Seefeld area (Tyrol, Austria) continued by fieldwork in September 2001. Samples of fresh black shale, retorted black shale, weathered black shale, soil and vegetation were taken in order to evaluate behavior of various heavy metals in the weathering process. The results of the study will be published in the Bulletin of the Czech Geological Survey in 2002.

A new project on the evaluation of the distribution of heavy metals in selected facies of black shales potentially suitable for combustion was launched within the Czech Technical Assistance Programme to Burkina Faso (Pasava et al. 2001).

Jan Pasava has co-organized and together with P. Dobes and K. Zak actively participated in the IGCP 429 Annual International Meeting (S-1), held in Cracow, Poland (August 26-29, 2001) within the framework of the 6th Biennial SGA - SEG Meeting.

Another very important aspect of the IGCP 429 activities - a "training component", was an active involvement in the preparation and technical programme of a training course for people from developing countries. IGCP 429 was together with the Czech Geological Survey in Prague, Government of the Czech Republic (through Technical Assistance Programme to Developing Countries), Czech Commission for UNESCO and the Division of Earth Sciences (UNESCO/Paris) one of the organizers and scientific guarantees of the GEOCHIM 2001 Postgraduate Certificated Training Course. The course was held in Prague and Dolni Rozinka (Czech Republic) from September 3 through September 17, 2001 and 12 geoscientists representing 7 countries were trained both theoretically and practically in the geochemical exploration methods and their environmental applications. Soil geochemistry, biogeochemistry and hydrogeochemistry including their environmental applications as well as up to date results on the role of organic matter in major environmental issues were lectured by J. Pasava, M. Duris, B. Kribek, M. Novak and J. Vesely (IGCP 429 members from the Czech Geological Survey).

B/ Projects with active working groups in the Czech Republic:

 

Project #454 - Medical Geology

Project Leaders: Olle Selinus and Peter Bobrowsky

Czech Representative: M. Duris (email: duris@cgu.cz)

The Czech Republic started its participation in the project in February this year. A working group was created, including the following 4 natural science organizations: The Charles University - Faculty of Science (Geochemistry, Geophysics), The Academy of Sciences of Czech Republic - Institute of Thermomechanics & Nuclear Physics Institute, Geofyzika enterprise, Brno,  Central Institute for Supervising and Testing in Agriculture and the following 3 medical establishment, i.e., Institute of Endocrinology, Prague, Regional Hygienic Station of Central Bohemia Region, Prague and Veterinary Research Institute, Brno.

It was agreed at the first Working Group meeting that a project proposal would be prepared by the end of the year. The proposal will be then submitted through the Ministry of Environment and with the support of medical and agricultural organizations to the Government Council for Science and Research with a request for financial support. The project will study the relationship between geological structure of an area (mining activities and associated pollution) and general public health in that area. Two area types will be compared - areas with heavily developed mining industry (Pribram, Kutna Hora) and areas with no mining pollution (Klatovy, Benesov). The introductory meetings, workshops & negotiations were characteristic for 2001.

 

Project #373 - Correlation, Anatomy and Magmatic-Hydrothermal Evolution of Ore-Bearing Felsic Igneous Systems in Eurasia

Project Leaders: R. Seltmann, R.I. Grauch and A. Kremenetsky

Czech Representative: M. Stemprok (email: stemprok@natur.cuni.cz)

Cooperation between the Faculty of Science of the Charles University in Prague and the Geological Institute of the Academy of Sciences of the Czech Republic in Prague brought important scientific results. Evaluation of data from the research and exploration programs of tin and tungsten deposits in the Krusne hory/Erzgebirge in 60 to 90tieth of the past century which have been so far little used or unused in scientific interpretations. Geochemical study of albite-rich Li-mica-topaz granite stocks in the Krusne hory Mts. (Czech Republic) revealed these bodies as products of extreme fractional crystallization with similar postmagmatic alteration styles: albitization and greisenization (Dolejs and Stemprok 2001). Their evolution was accompanied by interaction with waters of meteoric origin probably during the last stages of magmatic fractionation. Greisenization of mafic igneous rocks represented by lamprophyres was studied in Krupka. It proved Si and Al immobility during this alteration leading to origin of mica-rich metasomatites (Novak et al. 2001).

Project # 408 - Rocks and Minerals at Great Depth and on the Surface

Project Leaders: H.J. Kuempel, F. Mitrofanov and D.M. Gubermann

Czech Representative J. Trckova (email: trckova@irsm.cas.cz)

In the Laboratory of Geotechnics of the Institute of Rock Structure and Mechanics (Academy of Science, Czech Republic), homologues samples of metabasalts from the Karelian complex and of amphibolites from the Kola-Belomorian complex were studied in this year. Basic properties - density using the pycrometer method, bulk density on irregular specimens with paraffin wax cover up and porosity, which was calculated from density and bulk density of dry specimen were tested. The compressive strengths during uniaxial compressive loading were measured in two perpendicular directions - perpendicular to the layers and parallel to the layers. Axial and lateral strains were measured by electric resistance strain gauges during the tests. On the basis of strains measured under the cyclic (repeated) uniaxial loading, deformation modulus, Young's modulus and Poisson's ratio was determined. Comparison with values measured on the core samples from KSDB-3 was carried out. Agreement about common implementation of scientific-research investigation was signed with IGEM RAS, Moscow, Russia (Prof. Kazanski, Dr. Lobanov, Dr. Zharikov). Cooperation with the Institute of Geosciences, University of Kiel, Germany (Prof. Kern, Dr. Popp) continued.

Project # 410 - The Great Ordovician Biodiversification Events

Project Leaders: B. D. Webby, M. L. Droser and F. Paris

Czech Representative O. Fatka (email: fatka@natur.cuni.cz)

Activities of the Czech WG have successfully continued. The Czech scientists actively participated in the organization of the IGCP 410 major international meeting entitled Early Palaeozoic Palaeogeographies and Palaeobiogeographies of Western Europe and North Africa (September 2001, Lille, France) and in technical sessions and field trips. Oldrich Fatka was an official member of the Organizing Committee. A meeting and field trip were also held in Mongolian Gobi, where the Czech scientists also took part. These studies and discussions continued from the previous joint work in Russia (compare the report about the project 421) and significantly contributed to the understanding of the faunal bioprovincionalism and relationships of faunal patterns to paleolatitudes and climates (sections near Shar chuluut, Ongiin gol etc.).

Project #421 - North Gondwanan Mid-Palaeozoic Biodynamics

Project Leaders: R. Feist and J. A. Talent

Czech Representatives: J. Hladil (email: hladil@gli.cas.cz) and J. Kriz (email: kriz@cgu.cz)

Broad activities of the Czech WG have successfully continued and the project is coming to its terminal stage. The biostratigraphical and palaeogeographical studies were largely based on conodonts. For instance, the taxonomic evidence in the Lochkovian/Pragian boundary interval has been contributed by a new evidence and auxiliary insights. Chlupac and Oliver (1989) defined the Lochkovian-Pragian GSSP according to data from Weddige and Schoenlaub about the first entries of the index species Eognathodus sulcatus sulcatus, resp. eousulcatus, wchich were linked to the bed no. 12 in the Velka Chuchle Section. According to new investigations, the first occurrences of E. s. eosulcatus could occur somewhat lower in the section, than previously regarded. It means, that the GSSP point was set up slightly higher than possible entries of this taxon. But the point is, that in the bed no. 11 already appear also other typical Pragian species, e.g., the eta and beta morphs of L. steinachensis. The stratigraphic overlap of both morphotypes (older eta morph and its younger descendant beta morph) might indicate already Pragian sedimentation advanced in time. First occurrences of eta morph are close to lower Pragian boundary in Barrandian and in Carnic Alps, as it was pointed out earlier by Chlupac et al. (1985), and only higher up begin to overlap with beta morph. A detailed investigation of the stratotype and tracing the undulated biozene boundaries in the world (Spain, Asian part of Russia, SW of United States, etc.) contributed to the knowledge about time scales, paleoenvironments and seaways of the Early Devonian times (Slavik and Hladil 2001). The Czech working group regularly participates in the WG for subdivision of the Frasnian stage (J. Hladil) and WG for subdivision of the Emsian stage (I. Chlupac). Large capacity of work was concentrated on magnetosusceptibility, physical stratigraphy, magnetostratigraphy and also on problems of Devonian paleoenvironments - compare the list of relevant publications in appendix to this brief report. L. Slavik participated in three-week field meeting of the project in Novosibirsk (Rudnyi Altai Mountains, Kuznetsk Basin, etc.). A very close co-operation continued with the International Sub-commission for the Devonian Stratigraphy, SDS. Most of the studies are subsided from IGCP and IUGS branches in stratigraphy, both in ideas and small traveling expenses. Many subjects have been discussed and developed during the Bohemian Field Trip of the Senckenberg IGCP 421 Conference (I. Chlupac, J. Hladil, et al.). The guiding of the field trip was highly appreciated by participants.
